Now a branch of the Riggs National Bank, the Washington and Loan Trust Company is a commanding nine-story Romanesque Revival building located diagonally from the Patent Office Building (see DE15.2). The building's presence marks an abrupt transition on this thoroughfare between the classicism of the cluster of buildings defined by the Patent Office and the General Post Office and the surrounding buildings of Downtown East. The gray rock-faced granite ashlar gives a rich texture to the facade, over an internal frame of steel floor beams and cast-iron columns. Seen on the exterior, the lower two stories form the base of the design, the next four are treated as an elongated arcade, and the next two form a separate unit with flat-arch windows. At the top is a single story of small round-arch windows, the whole crowned by a modest cornice.
After leaving his position with the Supervising Architect's Office, Hill enjoyed a flourishing practice in Washington, designing buildings such as the massive Government Printing Office in the Romanesque Revival style and apartment houses and residences throughout the city.
